Novel rural household sewage treatment method

Abstract

The invention relates to a novel rural household sewage treatment method which comprises the following steps: 1) introducing rural household sewage into a grating, wherein the sewage enters a facultative pond if being filtered through a grating well; 2) introducing the sewage treated in the facultative pond into a biofilter, wherein a hairbrush elastic filter material fills the biofilter, the wavelength of the corrugated silk of the hairbrush elastic filter material is 160-200mm and the diameter of the silk is 2-5mm; 3) feeding the water filtered by the biofilter into an artificial wetland, wherein a matrix of the artificial wetland is composed of a pebble bed, the grain size of which is 50-100mm, a volcanic filter material layer, the grain size of which is 15-30mm, a biofilter material layer, the grain size of which is 8-10mm and a mud-free coarse sand layer, the grains size of which is 0.2-5mm from bottom to top successively, wherein iris wilsonii is placed in the artificial wetland; and 4) feeding the water treated in the artificial wetland into a biological pond, planting lotuses, hornwort and water lily in the ecological pond, and discharging effluent treated in the ecological pond out of a natural water body. The method provided by the invention is suitable for dispersed rural villages and stable in treatment effect, and can reduce diffusion of odors and breeding of flies and mosquitoes.

Description

technical field [0001] The invention relates to a novel rural domestic sewage treatment method, belonging to the technical field of sewage treatment. Background technique [0002] With the rapid development of the rural economy, the discharge of comprehensive wastewater in rural areas has gradually increased, which has made the environmental conditions in rural areas worsening and the environmental quality has declined significantly, directly threatening the living environment and health of the vast number of farmers, and restricting the healthy development of the rural economy. . The random discharge of domestic sewage is the main cause of rural water environment pollution, which seriously pollutes the rural ecological environment and directly threatens the health of farmers and the economic development of rural areas. [0003] my country's rural domestic sewage has the following characteristics: (1) Scattered and distributed in a large area. The geographical distribution...

Problems solved by technology

(3) Low processing efficiency

[0004] At present, there are many domestic and foreign treatment technologies for rural domestic sewage treatment, and the names are also various. However, both natural treatment systems and biological treatment systems have the problems of single technology and unstable treatment effects. At the same time, the treatment range is also limited, which is easy Smells and breeds mosquitoes
